Fitch has affirmed the BBB+ long-term ratings assigned to Converium Holding AG and its subsidiary Converium Holdings (North America), following the group's third quarter results.

Fitch also affirmed the BBB+ rating of the US$200m senior unsecured notes due in 2003 that originally had been issued by Zurich Reinsurance Centre Holdings.

The outlook on both ratings remains negative.

Fitch said it considered the third quarter results overall to be broadly in line with expectations and said it expected profitability to remain strong for the full year.
